Few Tips on How to Maintain Jaw Crusher

Jaw crusher is commonly known as “jaw breaker”, and is also called “Tiger Mouth”. Its crushing cavity is made up of dynamic jaw and static jaw, which simulates animals’ mouth exercising and helps finish breaking materials jobs. Jaw crusher is mainly used as coarse crusher and middle crusher in mine, building materials, capital construction and some other sections.Jaw crusher are equipped with one fixed and one movable crushing jaw (moving jaw),both of which support crushing plates support crushing plates (wearing parts) in several versions. They form a wedge-shaped crushing zone. The walls of the crushing zone are made of replace-able wearing sheets. Crushing is done between the two crushing jaws. The moving jaw of the single toggle jaw crusher moves elliptically. A pendulum motion is being carried out by the double toggle jaw crusher. The crushing force is produced by an eccentric shaft. Then it is transferred to the crushing zone via a toggle plate system and supported by the back wall of the housing of the machine. Spring pulling rods keep the whole system in a condition of non- positive connection.

Next we will introduce how to maintain jaw crusher.Turn off the jaw crusher regularly, examine the machine carefully. Check the inner abrasion condition of the much ion, such as central feed tube, conical cap, lining board on the upper or lower flow channel of the impeller, circular plate, and abrasion degree of the abrasive brick, change the serious abrasion assembly units in time, and repair these units. At the same time, pay attention to its weight, type, size, you must change them according to its usual parameter.Lubrication of the mechanical parts. Jaw crusher use Mobil automotive grease or three lithium base grease, add enough lubricating grease each 400 hours.; if works 2000 hours, open the principal axis matched bearings and get it washed; generally change a new bearing when it works 7200 hours.
